The washed-out colors kind of make it hip again, like the cinematography in The Killing. None of the kids ever worked again in show biz according to IMDB, but I remember D-list comic Michlin vaguely. As to the content, it's safe, earnest and not too corny stuff that kids should see and understand about themselves.
